Hi everybody, I'm crunching on a new DELL Latitude with Nvidia NVS 5200M (1024MB) driver: 320.49 OpenCL: 1.01 GPU and encounter driver restarts *only* at the end of a WU. On my other machines everything is fine, only on this laptop it happens. After the driver restart BOINC continues normal, but windows isn't "amused" about the driver restarts. :/ Any hints?

[edit]
It is this particular machine:

Maybe there is something different in Windows 8

The stderr_txt at the end seems OK:

Worker preemptively acknowledging a normal exit.->
called boinc_finish
Exit Status: 0
boinc_exit(): requesting safe worker shutdown ->
boinc_exit(): received safe worker shutdown acknowledge ->
Cuda threadsafe ExitProcess() initiated, rval 0

I don't know if this is relevant (or changed) for Windows 8

Edit:
There are some 'TDR changes in Windows 8':

Again I don't know if any of this is relevant to your case.
